Abstract
Recruitment of immune cells to adipose tissue is altered dramatically in obesity, which results in chronic inflammation of the adipose tissue that leads to metabolic disorders, such as insulin resistance and type 2 diabetes mellitus. The regulation of immune cell infiltration into adipose tissue has prophylactic and therapeutic implications for obesity-related diseases. We previously showed that naringenin, a citrus flavonoid, suppressed macrophage infiltration into adipose tissue by inhibiting monocyte chemoattractant protein-1 (MCP-1) expression in the progression phase to high-fat diet (HFD)-induced obesity. In the current study, we evaluated the effects of naringenin on neutrophil infiltration into adipose tissue, because neutrophils also infiltrate into adipose tissue in the progression phase to obesity. Naringenin suppressed neutrophil infiltration into adipose tissue induced by the short-term (2 weeks) feeding of a HFD to mice. Naringenin tended to inhibit the HFD-induced expression of several chemokines, including MCP-1 and MCP-3, in adipose tissue. Naringenin also inhibited MCP-3 expression in 3T3-L1 adipocytes and a co-culture of 3T3-L1 adipocytes and RAW264 macrophages. However, naringenin did not affect the expression of macrophage inflammatory protein-2 (MIP-2), an important chemokine for neutrophil migration and activation, in macrophages or in a co-culture of adipocytes and macrophages. Our results suggest that naringenin suppresses neutrophil infiltration into adipose tissue via the regulation of MCP-3 expression and macrophage infiltration.
摘 要
在肥胖中,免疫细胞向脂肪组织的募集发生了显著变化,导致脂肪组织的慢性炎症,导致代谢紊乱,如胰岛素抵抗和 2 型糖尿病。免疫细胞浸润脂肪组织的调节对肥胖相关疾病具有预防和治疗意义。我们以前的研究表明,柚皮素,一种柑橘类黄酮,通过抑制单核细胞趋化蛋白-1 (MCP-1) 表达抑制巨噬细胞浸润到脂肪组织在高脂饮食 (HFD) 的进展阶段。 -诱导肥胖。在目前的研究中,我们评估了柚皮素对中性粒细胞浸润到脂肪组织中的影响,因为中性粒细胞在进展阶段也渗入脂肪组织到肥胖。柚皮素抑制小鼠短期 (2 周) 喂养 HFD 诱导的中性粒细胞浸润到脂肪组织中。柚皮素倾向于抑制脂肪组织中 HFD 诱导的几种趋化因子的表达,包括 MCP-1 和 MCP-3。柚皮素也抑制 3T3-L1 脂肪细胞和 3T3-L1 脂肪细胞与 RAW264 巨噬细胞共培养的 MCP-3 表达。然而,柚皮素不影响巨噬细胞或脂肪细胞和巨噬细胞共培养物中巨噬细胞炎症蛋白-2 (MIP-2) 的表达,后者是中性粒细胞迁移和活化的重要趋化因子。我们的研究结果表明,柚皮素通过调节 MCP-3 的表达和巨噬细胞浸润抑制中性粒细胞向脂肪组织的浸润。
